Causes of blindness in Northern Tanzania: a hospital and rural health centre based study

Objective:To identify the main causes of blindness in Northern Tanzania.Methods:Ophthalmic patients at the Kilimanjaro Christian Medical Centre and on outreach clinics in the Kilimanjaro region of Northern Tanzania were examined. The cause of blindness was documented for any eye seeing less than 3/60 Snellen. If more than one factor contributed to the visual loss, the single factor deemed to be the most visually disabling was documented.Results:1045 blind eyes of 781 patients were examined. 264 patients were bilaterally blind. The main cause of bilateral blindness was cataract [39%]. The other chief causes of blindness were glaucoma, trauma and corneal scarring. The most important cause of corneal scarring, approximately half the cases, was microbial keratitis. Refractive error alone was responsible for 4.2% of bilateral blindness, of which 2.7% was uncorrectedpost-cataract surgery aphakia. Conclusions:Treatable causes of blindness, including cataract and refractive error account for over a third of all blindness in Northern Tanzania. Trauma, glaucoma and microbial keratitis are other important causes of blindness in the region.     

Causes of blindness and the results of cataract surgical intervention in the Micronesian islands: a retrospective study

Since 1983, we have delivered eye care to inhabitants of the Micronesia islands a total of 18 times over an 18-year period. Approximately 14,000 islanders were examined. We diagnosed a total of 1226 blind eyes and 1231 eyes with low vision. Unoperated cataract (n=765, 62.4%) was the leading cause of blindness in our data, and 611 cataract operations were performed. The preoperative visual acuity of the patients who underwent cataract surgery was less than 20/200. Visual acuity improved in 588 cases (96.2%) after the surgery. Sight-threatening complications occurred in 1.1% (7) of the eyes after the surgery, which is comparable to the rate in developed countries. Corneal opacity secondary to infection (11.2%) was the second leading cause of blindness in our data. Diabetic retinopathy (9.9%) was a cause of low vision in our data, and the number of eyes diagnosed with diabetic retinopathy in each district increased over the years. Glaucoma was the cause of blindness in 1.9% of the blind eyes, although the percentage may actually have been higher because visual loss was assessed only by reduced visual acuity. The demand for correcting refractive errors that caused a visual acuity of less than 20/60, was evident throughout the region. The majority of blind individuals in this study were suffering from operable cataract and good results were obtained with cataract surgery in this region. Further training of local medical staff would significantly improve eye care services in Micronesia.

Outcomes and Barriers to Uptake of Cataract Surgery in Rural Northern China: The Heilongjiang Eye Study

Purpose: To report visual outcomes and barriers to uptake of cataract surgery among subjects of all ages in Mingshui County, Heilongjiang Province, China.

Methods: Cluster sampling was used to select a cross-sectional sample of people living in the Heilongjiang Province. Each subject underwent a participant interview, presenting and best-corrected vision measurements and an ocular examination. Visual outcomes and barriers to uptake of cataract surgery were assessed among subjects undergoing cataract surgery. Individuals who needed cataract surgery were interviewed regarding barriers.

Results: Of 11,787 subjects, 10,384 eligible participants underwent visual acuity (VA) testing and a basic eye examination (88.1% response rate). The cross-sectional sub-sample of 21 participants receiving cataract surgery had a median age of 63 years. Six eyes undergoing surgery at the county hospital with conventional intracapsular and extracapsular cataract extraction without an intraocular lens implant were aphakic, and 15 eyes (71.4%) undergoing surgery at tertiary care hospitals were pseudophakic. Seven eyes (33.3%) had corrected VA?≥?20/60, and nine eyes (42.9%) had presenting VA?≥?20/60. Approximately 28.6% (6/21) had poor outcomes. The principal causes of presenting blindness after cataract surgery were refractive error/uncorrected aphakia and posterior capsular opacification. Cost was the most common barrier (73.9%) to uptake of cataract surgery.

Conclusions: Cataract surgical outcomes in northern China were poor. The principal barrier to uptake of cataract surgery was cost. These findings call for the establishment of cataract surgical services that are of high quality, affordable, and sensitive to high-risk groups.

Childhood blindness and severe visual impairment in Malaysia: a nationwide study

Aim

To determine the causes of childhood blindness and severe visual impairment (BL/SVI) in schools for the blind in Malaysia.

Methods

All children ≤15years attending 24 schools for the blind throughout the country were examined using the WHO Prevention of Blindness Programme (WHO/PBL) eye examination record for children, and visual loss was classified according to the International Classification of Disease (ICD).

Results

In all, 469 children were examined, of whom 448 (95.6%) had BL/SVI. The major causes of visual loss were retinal disorders (n=148, 33% mainly retinopathy of prematurity (n=78, 17.4%)), cataract/pseudophakia/aphakia (n=77, 17.2%), and anomalies affecting the whole globe. (n=86, 19.2%). The major underlying etiology was undetermined (n=193, 43.1%), followed by hereditary factors, 21.7% (mainly retinal dystrophies), and perinatal factors, 20.5%. More than 34 (7.6%) cases were considered potentially preventable and 192 (42.9%) potentially treatable.

Conclusion

Diseases of the retina are the major cause of visual impairment, with retinopathy of prematurity being an important avoidable cause. This reflects expansion of neonatal services in Malaysia, and improved survival of very low birth weight and preterm babies. Lens-related causes of visual impairment reflect the need to further improve pediatric ophthalmology services in Malaysia.

A multicentric cross-sectional study measuring the equity of cataract surgical services in three high-volume eyecare organizations in North India: Equitable cataract surgical rate as a new indicator

Purpose:Cataract remains the leading cause of blindness and visual impairment in most low-and middle-income countries, with the greatest burden borne by women. To achieve Global Action Plan targets, cataract programs must target people, especially women, with maximum need. This study examines whether cataract surgical programs in three major north Indian eyecare institutions are equitable and describes a refined indicator for reporting equity.Methods:Retrospective one-year cross-sectional study of cataract surgery utilization using routine administrative data from three north Indian eyecare institutions. Patient data were categorized by paying category, sex, and preoperative visual acuity. Comparisons were made between payment categories and sexes.Results:Out of the total number of patients operated, 86,230 were in the non-paying category and 56,738 in the paying category. Overall, 8.2% were blind, 21.1% were severely visual impaired (SVI) or worse, and 86.1% were moderate visual impaired (MVI) or worse. Non-paying patients had a significantly higher proportion of poorer visual categories compared to paying patients [(blind, 9.7% vs. 5.8%; SVI or worse, 24.6% vs. 15.8%; and MVI or worse, 89.1% vs. 81.6%, respectively, (P < 0.001)]. Women had significantly higher proportion of poorer visual categories than men [(blind, 8.9% vs. 7.4%, SVI or worse, 21.9% vs. 20.3% and MVI or worse 87.6 vs. 84.7%) (P < 0.001)].Conclusion:The institutions primarily provided surgery to patients with maximum need: too poor to pay, low visual acuity, and women. Similar data from all service providers of a region can help estimate the proposed “equitable cataract surgical rate”: the proportion of patients operated with maximum need among those operated in a year. This can be used for targeting people in need.
